Machine oil pressure sensor with built-in protective cover

Abstract

The invention relates to the technical field of machine oil pressure sensors, in particular to a machine oil pressure sensor with a built-in protective cover. The machine oil pressure sensor comprisesa mounting base and a pressure sensor body, wherein a first screw rod is fixedly connected to the bottom of the mounting base, a bearing plate is fixedly connected to the upper end of buffer columns,a first through groove is formed in the middle of the bearing plate, and connecting plates are fixedly connected to the middle portions of the left side and the right side of the inner wall of the first through groove respectively; and two clamping plates are rotatably connected to the outer side of each first shaft body through bearings, push plates are fixedly connected to the reverse sides ofthe two groups of clamping plates, a first mounting groove is formed in the upper portions of the left side and the right side of the inner wall of the first through groove respectively, a second screw rod is rotatably connected to the inner wall of each first mounting groove through a bearing, an extrusion block matched with the push plate is in threaded connection with the outer side of each second screw rod, and the protective cover is arranged at the upper end of the bearing plate. The machine oil pressure sensor has strong practicability and functionality, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of engine oil pressure sensors, in particular to an engine oil pressure sensor with a built-in protective cover. Background technique [0002] The oil pressure sensor of a car is an important device for detecting the oil pressure of the vehicle engine. The detected data can help control the normal operation of the engine. The electronic oil pressure sensor consists of a thick film pressure sensor chip, a signal processing circuit, a housing, and a fixed circuit board. device and 2 lead wires (signal wire and alarm wire). The signal processing circuit is composed of power supply circuit, sensor compensation circuit, zero adjustment circuit, voltage amplification circuit, current amplification circuit, filter circuit and alarm circuit.

AI Technical Summary

Problems solved by technology

[0003] At present, the existing automobile oil pressure sensor can be installed on the main oil passage of the engine with the mount, but in actual use, the mount will vibrate with the movement of the car, because the mount lacks protection such as a protective cover inside the mount measures, which will cause damage to the sensor due to vibration and external pressure; in addition, in the existing technology, when the oil pressure sensor is damaged, most of the staff need to disassemble the mounting seat and the pressure sensor body together, resulting in a disassembly speed Slow, time-consuming and labor-intensive, cannot meet the needs of use well
